You could also get some of the ear muff style headphones, that, incomjunction with the ear plugs would save your ears quite a bit.

I guess it depends on how old you are how you feel about this, but I would like to keep my hearing throughout my life. The levels those engines are at requires ear protection. Believe me, you can still "feel" the noise with ear plugs on. And you can hear the ludspeakers fine, except on qualifying day, which is when you REALLY need earplugs. So I say, listen to GGG. He needs his ears for work, so he knows what he's talking about.

Like ggg says, I'd recommend the foam rubber type, usually provide 29-30db of attenuation.

You can buy just crappy little earplugs that construction or factory workers use, that will be fine. I also find it is not as bad on race day when the cars are relatively "together". During practice and qualifying all the drivers are positioning themselves to get a clear run, so it is basically car after car after car. A bit much.

I wore earplugs at the last Canadian gp (hairpin again) and have had no problems. Still, I would take them out once in a while just to hear the raw sound. It seems that submitting your ears to that kind of punishment for 2 hours is the big problem. So, like leroy said, use them but also listen to the sound w/out.
Like others have said, it does depend on where you're sitting.

As my friends and I where walking towards our seats we heard the first F1 cars being started from about 80m away.
Hmm thats loud they mused. Me having been before was ready and had my tiny ear plugs around my neck.
As we aproached out stand (senna stand, final corner onto the straight) the first car screamed by.
My friends got excited by the noise, and rushed to their seats (its their first GP).
Now we are sitting 6-8 meters from the wall the cars come up to real close as they exit the corner at full throttle while changing gears.
I put on my plugs and waited excitedly.
Next car came by, Benatton i think, my friends swore loudly and attemped to block thier ears while running away from the stand. I laughed when they come back with thier $1 ear plugs.
Ok story over. Its loud! Ear piercing, brain thumping loud! I was shocked when i first heard an F1 engine. I suggest u listen to it once then but in your ear plugs

Of coure if you are in a slowish section or fairly far back up the stand you dont really need them so much as the noise is far from ovrewhelming

And all this was due to noice of about 80-100dB. Imagine what a 140dB-F1-engine can do. (Keep in mind: plus 3dB doubles the noise!)
Don't be stupid.

Having been standing track-side for about 30 years, my advice is to use ear plugs or ear defenders - tinitus certainly isn't a good thing - I speak from experience...
Some circuits even give away ear plugs for free - they certainly give a reasonable level of protection.
I don't know if they will be broadcasting the commentary on radio at Indy, but if they are, the best thing to use is a pair of 'goofy type' ear defenders with a radio earpiece inside - that way you get protection and can still hear the commentary.

The story about the 80dB whistling is very good, and I hope that it helps a few people.
I had the start of a whistle, very quiet, but I'm a "Listener" by profession, and am very sensitive/critical about my listening apparatus. I now have to wear ear plugs when driving and on city streets. The whistle has now gone away, but I have to maintain this minor inconvenience to avoid tinnitus.

This is what I did twice at the Canadian GP and that's what I would do if I were going to the US GP.
You should ask Damop about the type of earplugs he was wearing. They were really comfy and they did offer good protection.

ps I think if your seats are under the covered grandstands the noise will be MUCH louder.

Loads of people will have them - you won't be alone.
Better to have them and not need them then the other way around ...

Could the noise be much less intense now because you went to 43 GPs and never used ear plugs?;)

I would suggest some sort of ear protection if you want to keep you hearing.

Noise levels decrease by 6 db with every doubling of distance so the close (<30 m) exposure at trackside lasts a very short time per vehicle. This works out to about 1 second per car or about 20 second per 90 second lap.
The difference between listening from 30 m and 1 m where levels exceed 130 db is about 36 db which gives a level of about 100 db at trackside. Three vehicles in this zone give about 104 db. This is equivalent to a very loud passage by a symphonic orchestra and in no way comparable to a rock band or even a high powered stereo.
Of course exposure to constant sound of levels of 100 db for hours per week will cause hearing loss but racing cars don't produce a constant level at track side so the net exposure is quite low. If one is fortunate enough to watch a F1 race from less than 30 m, more than your hearing is in danger (Remember Monza this year) and I would suggest moving back for other reasons than hearing loss!

It is worthwhile to listen for a couple of laps without plugs, but you will need them for the long haul. As an engineer I work with a lot of equipment operators and all of these dudes have hearing aids because of the machinery noise. I always wear hearing protection around very load equipment because I firmly believe in the expression "Cock suckers are deaf".

Then as cars spread out and the noise gets more constant I don't think it is worth jeopardizing my hearing any longer. Earplugs go in.
A little risk is worth it at the start, but have earplugs for the long haul. I have already lost enough hearing to know it is not to be trifled with. Anykind will do from shooting plugs to the simple foam ones.
As several people said distance does matter, but I used to live 10 Km's from Hockenheim and would be awakened on Saturday morning by the sound of free practice.

You say that a car producing 130 dB will be producing 36 dB at 30m at the race track. WRONG!
130dB is basically the output of a jet engine, 36dB is basically the SPL (sound pressure level) experienced in a quite room, like a bedroom at night (without any "guests...if you know what I mean). Your conclusion is wrong.
Acoustic power drops 6dB per doubling of distance assuming sphereical radiation, which is not the case at the race track. First off, you only radiate over half of a sphere (you don't lose that much through the ground) and then on top of the you are surrounded by reflective surfaces at the race track.
I won't go any farther, don't want to bore any reader here. Suffice it to say, it is really loud at the track, and rarely drops below 85dB SPL, which is roughly the sound level on a busy city street, and can easily peak at 130 to 140 SPL, the threshold of pain.

Chris, I am sorry, but I fail to see how you can say I am wrong that the 12 cilinders boxers in the late 70s, early 80s were more rumorous. I have heard them back then and I have heard current engines. Current engines produce more noise than the good old 8 cilinder Ford Cosworth, but Ferrari, Alfa and Matra had far more noisy units. Did you actually hear them live at a GP or you are just speculating from you couch? in Monza and Imola the Alfas were insanely loud.

This really scared me because it directly impacts my job performance. But I just want people to know that "it's just for and hour and a half" isn't a valid argument. It can cause permanent, and really irritating, damage.
